DC Motor Speed Controller 6–28V 3A with PWM Adjustment

This compact and efficient DC motor speed controller allows precise control of motor speed using PWM (Pulse Width Modulation) technology. With an input voltage range of 6V to 28V DC and a maximum current capacity of 3A, it is ideal for small DC motors and low-voltage lighting control.

Key Features:

• Input Voltage: 6–28V DC
• Maximum Current: 3A
• Speed Control Mode: Stepless PWM adjustment
• Adjustable Duty Cycle: 0% to 100%
• Control Method: Potentiometer with built-in ON/OFF switch (click to power on, rotate to increase speed)
• Application: Suitable for motor speed control and compatible LED dimming (with proper current limiting)

Switch Function:

The potentiometer features a built-in click switch. Turning the knob clockwise from the leftmost position switches the device ON and continues to adjust the motor speed from 0% to 100%.

Important Notes:

• This controller is primarily designed for DC motor speed regulation.
• For LED dimming applications, ensure the LED supports direct power control and always use a current-limiting resistor to prevent damage.
• Incorrect use for LEDs without proper resistance may burn out the dimmer circuit.

Ideal for DIY electronics, model cars, fans, and other small DC motor projects, this controller offers reliable and smooth speed control in a compact form factor.
